Re: AMP can have 1 and only 1 VDisk but can have many Physical Disk

Hi Rishi,

As you know teradata is SHARED NOTHING architecture, each amp has its own VDISK space which is managed and control by itself. As this is logical disk space there is no point in having more than one logical space for each amp. Also the mapping of AMP to its VDISK is one to one.

I can add up one more point, if you assume more than 1 VDISK for each amp, output of hasing map algorithm becomes much more complex which is not much appreciated.
